@zon,

When you load a battery it will increase in voltage because the internal resistance is
going down a bit. Then the voltage will start to fall again. Do a test, connect a 10 Watt
light bulb to a 12 volt battery. Measure the voltage and see for yourself. First the voltage
climbs because of the load is generating a small heat inside the battery thus lowering
the internal resistance. After a while the charge is going down and the voltage drops.

Nice circuit by the way!  :D

Groundloop.

@Koen1,

If you have a better explaination, please share.  :D

No, but I was just wondering what mechanism is at work there
if it is really the case that the temporary increase in temperature
decreases the resistance,
because in general temperature increase leads to increased resistance.
I know that this temperature dependant behaviour can be very different
in electrolytes, but I have no specific info about that mechanism nor
about a negative temperature coefficient for resistance of the electrolytes
used in rechargeable batteries.
Do you?

@Koen1,

Only by observation. I have noticed that batteries goes up in voltage when loaded.
Then after some time the voltage drops again. I have seen this numerous times.
This effect has fooled many free energy researchers to believe there is o/u at play.

Think about it, a lead acid battery has a much higher charge output when warm than cold.

If I may comment on the developments, I thought that the purpose of this thread is to focus on *practical* applications?
I know it's fun connecting an aerial and the ground and collecting whatever emissions are in the air, but that is totally impractical in most real world applications. You are definitely not going to use a flashlight, or any light emission device, that needs a 2m aerial and another wire to the ground, at all times.

@ Amigo:

No, but you could recharge such devices in this manner, as we are doing with the earth batteries.  you can charge batteries and caps....for free.

@amigo

I'm agree, that's funny using that circuit flash flight purpose. I'm only to try the my friend's concept.
He will arrive at my place next 2 week. I will post what i can get it from him.

I think this is a decent platform for experimenting.  Zon is always making new circuits so I think his results are interesting.

Remember, marco suggested we add a sub-milimeter spark gap using mechanical pencil graphite.  I want to build one of these, but need to get access to a microscope.

Hey the long arial is not that important.
The spark gap is.
It just needs some wire it does not have to be miles.
A regular crock clip wire works fine.

Hi it is intresting you mention this.
What about boiling the acid and keep it under reflux so it condenses back into the battery..
We know the electrons move faster when hot so this would be Direct Heat into Electricity conversion...
Would that improve the battery's behaviour in a sense it does not go dead??

@-[marco]-,

I think boiling acid will be dangerous!
This is NOT something one should attempt to do in a home lab.

Well, that is your personal opinion.

There are a lot of things that are labeld "Dangerous"

Then how about a semi-pro opinion :)

I can really say I know something about the subject because my mother is a chemistry professor and so most of the earlier days of my life I have spent around chemicals and been taught about them...

Some things should simply not be performed in your home. Without adequate environment if anything goes wrong you could mess yourself up pretty badly very fast, or succumb to injuries even. One can never be too careful, especially if you are physically present around corrosive chemicals and/or do not have proper haz-mat training/knowledge. Events can occur in a blink of an eye and without drilled training most people will do stupid things trying to remedy already a bad situation.

Always good advice.  Some may listen, some may not, but at least you tried and I think that is honorable.
